Common Questions
Frequently Asked About Custom Software Development.
Depends on scope. Simple internal tools: 4–8 weeks. SaaS MVPs: 3–6 months. Enterprise platforms: 6–18 months. We give a fixed-scope proposal within 7 days of our discovery call so you know exactly what you're committing to before work starts.
Three things: (1) Code that passes review by senior engineers — no quick hacks that break in six months. (2) Automated test coverage on critical paths so bugs don't ship to users. (3) Infrastructure that scales predictably and recovers gracefully when things go wrong. Production-grade is the difference between "it works in our dev environment" and "it works when your business depends on it."
Both. We do greenfield builds, but we also inherit codebases regularly — adding features, modernizing aging systems, refactoring to handle scale. A Code & Architecture Audit is the typical first step on existing codebases.
You do, from Day 1. All code, infrastructure, and IP is in your name. We set up your AWS, GitHub, and other accounts under your control and add ourselves as admins — never the other way around. You're never locked in or held hostage by access we control.
Yes. Most clients move from project mode (Fixed Scope) to ongoing development (Managed Retainer) after launch. We maintain, iterate, and grow software we've built — and we can take over maintenance of systems we didn't build.
Yes. Every modern business has 10+ systems that need to talk to each other. We integrate with Salesforce, HubSpot, NetSuite, Stripe, QuickBooks, and dozens of other platforms via APIs, webhooks, and direct integration. Custom connectors when no public API exists.
Custom Software is broader — includes web apps but also covers internal tools, SaaS platforms, API backends, complex business logic, and integrations. Web Development specifically covers marketing sites, public-facing web apps, and content platforms. If you need a marketing site, that's Web Development. If you need a platform that handles your operations, that's Custom Software.
